Looking for code help

[Jboden615]

1998 XJ 4.0 automatic just bought this XJ ( first one) had new plugs and wires with cap but was still missing on #3. I installed new fuel injectors and a tps. Now keep getting codes of injector circuit malfunction from p0201-p0205 normally 2 at a time. Not sure which way to go next. Also did switch the computer with one from another Jeep but that did nothing for my problems. Any help is greatly appreciated

Could be wiring, have you had a good look at the harness? I think I'd do a compression check on all the cylinders as well.

Oh and one more thing, are you loosing any coolant?
